[Patch v4 0/7] Transition of fsl qspi driver to spi-mem framework

[Kuldeep Singh]

This entire patch series migrate freescale qspi driver to spi-mem
framework.

v4 version of series include removal of buildman failure on LS2080AQDS
build which was observed in cleanup patches. Also, more clear commit
message of patch 5.

v3 version of series includes correction of copyright in qspi driver and
also move SPI_FLASH_SPANSION from header to defconfigs in same patch.

v2 version of series includes changes in qspi driver to have 1k size
instead of complete flash size so as to make driver independent of flash
size. This also makes it align with linux version of driver. Also added
support for imx platforms to set TDH bits correctly. There are other minor
changes in commit messages.

Dependency on patches[1][2]. These patches are required to resolve booting
crash observed in LS1012ARDB. One crash was related to pfe driver as it was
accessing flash memory directly and other was based on environment.

Patch 1 adds new qspi driver incorporating spi-mem framework and also
removal of old driver which was based on spi-nor. The driver is a ported
version of linux qspi driver. Initial port was done by Frieder. Now, no
more direct memory access to spi-nor memory is possible i.e accessing flash
memory using absolute address is not possible.

Patch 2 removes unused qspi config options.

Patch 3 moves FSL_QSPI to defconfig instead of defining it in header files.

Patch 4 removes unused num-cs property from imx platforms.

Patch 5 enables SPI_FLASH_SPANSION in ls1012a defconfig as FSL_QSPI is
already enabled.

Patch 6 enables SPI_FLASH_SPANSION in defconfigs of LS1046a boards instead
of defining in header files.

Patch 7 updates the device-tree properties treewide for layerscape boards
by aligning with linux device-tree properties.
